The "Local Karuta Cards Collection" preserved at the Library and Information Technology Center, Gunma University, consists of over 270 types of karuta cards, including those generously donated by Mr. Yukio Yamaguchi, Chairman of the NPO Japan Local Karuta Association, and Ms. Mikiko Haraguchi, Vice Chairman of the same association, as well as donations from individuals and local municipalities.

    Within the collection, there are more than 70 types of karuta cards related to Gunma Prefecture, including the "Jōmō Karuta: local karuta cards in Gunma" series, and over 200 types of karuta cards from various regions throughout Japan, ranging from Hokkaido to Kyushu, showcasing the rich regional diversity. The collection has been praised as the largest of its kind in Japan.

    During the late 2017 to early 2018, the Library hosted the "Exhibition of Japan's Largest Karuta Collection," which received positive feedback, with visitors coming from outside the prefecture. The Local Karuta Collection is stored in a special materials room, but if you inquire with the library in advance, you can have the opportunity to view the actual cards.
